Flashcards in EMBRYOLOGY The menstruation cycle Deck (9):
1

FSH

  • Follicle Stimmulating Hormone

Origin: Pituitary Gland / Hypophysis

Effect: + Triggers developement of follicles and growth

Cycle Starts!

2

LH

  • Luteinising Hormone (Lutein=yellow)

Origin: Pituitary gland / Hypophysis

Effect: + Stimulates growth of follicle

+ increases oestrogen release

3

Oestrogen

origin: follicle

Effect: - release of FSH

+ release of LH

+ growth of follicle

+ promotes growth of uterine lining

4

Progesterone

origin: Corpus Luteum (yellow)

Effect: - Inhibits FSH secretion

-inhibits LH secretion

+ stimulates developement of uterus and mammary glands -> uphold pregnancy

5

HCG

HUMAN CHORONIC GONADOTROPIN

origin: Embryo / fetus

Effect: + prevents degeneration of corpus luteum

-> I exist!
